70mai brings native 4K to both sides of the car with A900 Ultra dash cam

The A900 Ultra pairs dual Sony STARVIS 2 sensors with low-latency 4K rear video, 4G cloud access and up to 30 days of parking protection with an optional battery pack.

70mai has refreshed its flagship dash cam range with the A900 and A900 Ultra, two dual-channel models built around true 4K HDR recording at the front and rear. According to HWUpgrade, which tested both units ahead of launch around IFA 2026, the update is intended to close a common gap in the market: many products marketed as 4K still rely on upscaling, whereas 70mai is claiming native 4K capture on both channels for sharper licence plate detail and more reliable evidence footage.

The more advanced A900 Ultra is the clearer technical step up. As 70mai’s product information indicates, it uses two Sony STARVIS 2 IMX678 sensors and records at 30 frames per second without interpolation, with a 130-degree field of view at both ends of the car. The company also says the rear camera can be linked through LVDS rather than the more common AHD approach, allowing uncompressed 4K video transmission with only 20 milliseconds of latency. In practical terms, that should make the rear image much more immediate in live view and during reversing manoeuvres.

HWUpgrade reported that the Ultra also adds a 3-inch integrated display for menu control and a live rear feed, while keeping the body compact enough to sit discreetly behind the rear-view mirror. The same report noted that both cameras are designed for unobtrusive installation, but the Ultra is the version aimed at buyers who want the strongest image pipeline and the most responsive rear channel. 70mai’s own material also highlights HDR scheduling, manual EV adjustment and its MaiColor Vivid+ Solution 2.0 and Night Owl Vision 2.0 processing tools, both intended to improve contrast and licence plate visibility in difficult light.

Parking surveillance is another area where the new range is positioned aggressively. According to 70mai and independent coverage by Camera Times, the A900 Ultra uses a supercapacitor rather than a lithium battery for better heat tolerance, with standby power consumption of just 5 mA. When paired with the optional Battery Pack Mini, 70mai says the system can provide up to 30 days of parking protection under laboratory conditions, using collision-triggered recording rather than continuous high-drain operation. The company also offers a time-lapse parking mode and buffered emergency recording that can capture moments before and after an impact.

Connectivity has also been updated across the range. HWUpgrade and 70mai both point to a revised 4G Cloud+ 2.0 platform, Wi-Fi 6 for faster file transfer, built-in GPS and voice control. The company says remote access through the app can include live viewing and playback, while the Ultra adds two-way voice communication. 70mai’s wider product pages also confirm support for microSD cards up to 512 GB and positioning data from a five-system GPS setup. The A900, meanwhile, keeps the same dual-4K HDR concept but uses a simpler front camera with a large f/1.55 aperture and is pitched as the less expensive route into the new range.

The package strategy is clearly designed to cover different buyer needs. HWUpgrade said the A900 Ultra can be bought as a full bundle with rear camera, GPS and 4G kit, Battery Pack Mini and 128 GB storage, while the A900 is also sold more simply through retail channels. For buyers choosing between them, the Ultra is the more complete platform for low-light capture, parking surveillance and rear-feed performance, while the A900 remains a high-spec dual-4K option with the core features intact.
